The Trouser Expander is the perfect gag gift for anyone with a deflated ego. The penis-esque air bag fits comfortably in your pants and expands on demand with the handheld pump. At around $8, it’s the cheapest way to increase the size of your trouser snake without pills, creams, or surgery. The Trouser Expander gives you an added 8 inches of length and some serious gerth-age. Great for hitting on girls at a bar or for boosting your confidence while on the prowl.
